…the wise souls who are aware of the essential relationships emanating from the realities of things consider that one single matter cannot, by itself, influence the human reality as it ought and should, for until the minds of men become united, no important matter can be accomplished. At present universal peace is a matter of great importance, but unity of conscience is essential, so that the foundation of this matter may become secure, its establishment firm and its edifice strong. 
- ‘Abdu’l-Baha  (From the First Tablet to the Hague, 17 December 1919; revised translation under the direction of the Universal House of Justice, available at the online ‘Baha’i Reference Library’ site of the Baha’i World Center)
